Abstract

L'invention concerne une composition de polyéthylène comprenant le produit de réaction de l'éthylène et éventuellement d'un ou de plusieurs comonomères d'alpha-oléfine en présence d'une composition de catalyseur comprenant un procatalyseur multi-métallique par l'intermédiaire d'une polymérisation en solution. Ladite composition de polyéthylène est caractérisée par une ou plusieurs des propriétés suivantes : un indice de fluidité, I2, mesuré selon la norme ASTM D 1238 (2,16 kg à 190 °C), de 0,9 à 5 g/10 min ; une masse volumique (mesurée selon la norme ASTM D792) de 0,910 à 0,935 g/cm3 ; un rapport de fluidité à chaud, I10/I2, I10 étant mesuré selon la norme ASTM D 1238 (10 kg à 190 °C), de 6 à 7,4 ; et une distribution de poids moléculaire (Mw/Mn) de 2,5 à 3,5.
